Crystal methamphetamine is an addictive stimulant that affects the central nervous system, stimulating the release of neurotransmitters in the brain. Long-term use can damage the brain's ability to produce these neurotransmitters naturally, leading to addiction and depression. Crystal meth use initially creates a feeling of euphoria, increased energy and well-being, in addition to anxiety, paranoia, diminished judgment and irritability. Other effects include many physical and psychological symptoms.
Stimulation
Certainly the most notable effect of crystal meth is increased energy and hyperactivity. Darryl Inaba and William Cohen, addiction experts and authors of "Uppers, Downers, All-Arounders," explain that people using meth feel no need for sleep, and may have boundless energy that they may expel in dancing, exercising, rapid-fire talking or on tasks such as cleaning. A crystal meth high can last for up to 12 hours. Even after the drug has worn off, users often experience lingering agitation, restlessness and insomnia.
Hostility
Crystal meth use may cause hostility and aggression. Inaba and Cohen warn that particularly with higher dose or longer-term use, aggression and violence may occur. Meth causes irritability and decreased judgment, and this combined with paranoia can lead to misinterpretation of others' actions, and aggressive reactions to perceived threats.
Agitation
People using crystal meth usually display numerous signs of physical and psychological agitation. These may include teeth-grinding, paranoia, fear, quick startle response, restlessness and insomnia, according to Inaba and Cohen. A user's attempts to soothe agitation may manifest in repetitive behaviors, the use of alcohol or marijuana, or a strong need to control his or her environment.
Psychotic Behavior
Longer term or higher dose usage can cause psychotic behavior. Hallucinations, delusions and paranoia may all occur. The nonprofit Partnership for a Drug-Free America describes how some users feel the sensation of bugs on their skin, and scratch ceaselessly at their bodies. Psychotic rages can occur. Crystal meth may cause pressured, confused speech. All these psychotic symptoms may be nearly indistinguishable from schizophrenia, according to Inaba and Cohen. Narconon explains that these psychotic states may lead to violent or suicidal behavior.
